Back at the Education Research Guide look for the blue tabs that say “Web Resources” and “Education Statistics.” On these pages you will find some helpful links for information and statistics on urban schools and measures to improve them. Particularly, look at the National Center for Education Statistics linked from the Education Statistics tab.
